agent-creator

SkillAI & models

Use when creating expert agents. Generates agent.md with frontmatter, hooks, required sections, and skill references.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the agent-creator skill

What this skill tells your AI

The instructions your AI receives, as published by fusengine/agents in plugins/ai-pilot/skills/agent-creator/SKILL.md and read by ahel’s review.

It does not create the skills an agent references -- for that, use skill-creator; agent-creator only wires the agent frontmatter and workflow around skills that already exist or are created alongside it.

Agent Creator

Agent Workflow (MANDATORY)

Before ANY agent creation, delegate via Agent — spawn 2 agents in parallel (single message, 2 Agent calls). Generated agents carry Agent and SendMessage in their tools, so this same pattern is what they must use internally too:

  1. fuse-ai-pilot:explore-codebase - Check existing agents, analyze patterns
  2. fuse-ai-pilot:research-expert - Fetch latest agent conventions

mcp__context7__query-docs is a direct MCP call, not a spawned agent — invoke it directly (alongside the 2 Task calls) to get examples from existing agents.

After creation, run fuse-ai-pilot:sniper for validation.


Overview

ActionWhen to Use
New AgentNew domain/framework expert needed
AdaptCopy from similar agent (Next.js → React)
UpdateAdd skills, modify hooks

Critical Rules

  1. ALL content in English - Never French or other languages
  2. Frontmatter complete - name, description, model, tools, skills, hooks
  3. Agent Workflow section - Always first content section
  4. SOLID rules reference - Link to solid-[stack] skill
  5. Register in marketplace.json - Or agent won't load
  6. Hook scripts executable - chmod +x
  7. Output Format section mandatory - Every generated agent must define a standard ## Output Format section (status, files_changed, errors, sources) — an agent invoked by a lead must return structured data, not prose

Quick Reference

Create New Agent

# 1. Research existing agents
→ explore-codebase + research-expert

# 2. Create files
touch plugins/<plugin>/agents/<agent-name>.md
touch plugins/<plugin>/scripts/validate-<stack>-solid.sh
chmod +x plugins/<plugin>/scripts/*.sh

# 3. Register in marketplace.json

# 4. Validate
→ sniper

Adapt Existing Agent

# 1. Copy similar agent
cp plugins/nextjs-expert/agents/nextjs-expert.md plugins/new-plugin/agents/new-expert.md

# 2. Adapt with sed
sed -i '' "s/nextjs/newstack/g; s/Next\.js/NewStack/g" agents/new-expert.md

# 3. Update skills, tools, register

Validation Checklist

  • ALL content in English
  • Frontmatter complete (name, description, model, tools, skills)
  • Agent Workflow section present
  • Mandatory Skills Usage table
  • SOLID Rules reference to solid-[stack]
  • Local Documentation paths valid
  • Output Format section present (status, files_changed, errors, sources)
  • Hook scripts executable
  • Registered in marketplace.json

Related: Skill Creator

When creating an agent, you often need to create skills too.

Use /fuse-ai-pilot:skill-creator to create skills for the agent:

ScenarioAction
New agent needs skillsCreate skills with skill-creator first
Agent references skillsEnsure skills exist in skills/
Adapting agentAdapt related skills too

Best Practices

DO

  • Use skill-creator for associated skills
  • Reference solid-[stack] skill for SOLID rules
  • Include Gemini Design section for UI agents
  • Make hook scripts executable

DON'T

  • Write in French (English only)
  • Skip Agent Workflow section
  • Forget marketplace registration
  • Create agent without its skills
  • Hard-code paths in hooks (use $CLAUDE_PLUGIN_ROOT)
